If f(x) = 3x - 9 and g(x) = x², what is (gºf)(5)?

36

Step-by-step explanation:

Here, f(x) is the input to g(x), forming a composite function.

To evaluate  (gºf)(5),

1) find the value of f(5).  It is f(5) = 6.

2) Use this result as the input to g(x):  g(6) = (6)^2 = 36

y = 0.77(x)

step-by-step explanation:

the jacket retains this value after 23% cut or retains 77% of original value. plug original 87 jacket price for x and the remaining value should be y.
